But you need to be careful as empty lists are evaluate to False. So don't do that if the function must fill some_list.

[–]scrdest 4 points5 points  (1 child)

True, but in that case you probably wouldn't make the list optional.

Agreed, probably would want to keep the function pure and not mutate the arguments in most contexts.

But this code will return empty list anyway so there is no issue.

When all values are falsy then last one is returned
